Time Averaging Meets Labor Supplies of Heckman, Lochner, and Taber
We incorporate time-averaging into the canonical model of Heckman, Lochner, and Taber (1998) (HLT) to study retirement decisions, government policies, and their interaction with the aggregate labor supply elasticity. The HLT model forced all agents to retire at age 65, while our model allows them to choose career lengths. A benchmark social security system puts all of our workers at corner solutions of their career-length choice problems and lets our model reproduce HLT model outcomes. But alternative tax and social security arrangements dislodge some agents from those corners, bringing ...

Money does Granger-cause output in the bivariate output-money relation
A bivariate Granger-causality test on money and output finds statistically significant causality when data are measured in log levels, but not when they are measured in first differences of the logs. Which of these results is right? The answer to that question matters because a finding of no Granger-causality from money to output would substantially embarrass existing business cycle models in which money plays an important role [Eichenbaum and Singleton (1986)]. Monte Carlo simulation experiments indicate that, most probably, the first difference results reflect lack of power, whereas the ...

Catching with the Keynesians
This paper examines the role for tax policies in productivity-shock driven economies with "catching-up-with-the-Joneses" utility functions. The optimal tax policy is shown to affect the economy counter-cyclically via procyclical taxes, i.e., "cooling down" the economy with higher taxes when it is "overheating" in booms and "stimulating" the economy with lower taxes in recessions to keep consumption up. Thus, models with catching-up-with-the-Joneses utility functions call for traditional Keynesian demand management policies. Parameter values from Campbell and Cochrane (1995) are also ...

A supply-side explanation of European unemployment
This article offers a supply-side explanation of striking patterns in unemployment rates and duration of unemployment in European countries, compared with other member countries of the OECD (Organization for Economic Cooperation and Development). The rise in long-term unemployment in Europe is attributed to the adverse incentive effects of generous welfare programs in times of economic turbulence.
